T 0 all whom it may concern; a

Be it known that I, HENRY HIGGIN, a citizen of the United States, and a resident of the city of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in Veather-Strips for Windows, of which the following is a specification.

The first object of my invention is to provide a .device which can be combined with windows and with doors, and which shall, in connection with such window or door, effectually exclude dust, air, moisture or liquid from the room, chamber or apartment provided with such window .or door.

One of the objects of my invention is t provide a weather strip which shall he .durable.

Another of the objects of my invention is to provide a metallic insert whose back or rear edge shall not oscillate, but shall be held fixedly and firmly to the back of the groove in which the insert is located.

Another object of my invention is to reduce the friction between parts that come into contact.

Another object of my invention is a formation {and arrangement whereby the lower portion of those sides ,or portions ofthe insert which extend in the groove from the back of the insert to the mouth of the groove conform in shape to the curved porthe various advantages derived from their use conjoint ly or otherwise will be apparent from the following description and claims. In the accompanying drawing making a part of this specification, and in which similar characters of reference indicate corresponding parts,Figure 1' is a perspective view of a corner portion of a window frame and attachments. Fi 2 is a vertical croSS' section of a window frame and bf an adjacent portion of a window sash combined with my invention. In Figs. 1 and 2, the grain of the sectioned sides of the wood is shown. Fig. 3 is a perspective view of a short length of the flan ed metal strip. Fig. l is a short length of tlge metal piece, herein denominated the insert. Fig. 5 is an end elevation of the groove. Fig.,,6 is an end elevation of the insert. Fig. '1 is an end elevationof the insert in place in the groove, as it is in practice and in readiness to receive the tongue for closing or sealing the joint between the window or door and the frame adjacent to said window or door. Fig. 8 is an end elevation of the groove and of the insert in place in the groove, and of an end elevation of the sealin tongue or rib attached to one of the mem .ers of the window, and inserted in the insert, in working position, Fig. 9 is an end elevation in cross section, illustrating a onstruction modified in a specific feature. 10 is an end elevation in .cross section, o the grooved meniher and the insert within the groove, showing a simplified form of construction.

will now proceed to describe my invention in detail.

A indicates a portion of the length of the bottom piece of a window frame or casing.

13 indicates a portion of the length of either one of thfi upright parts or sides of the window frame.

B indicates the well known groove in a vertical portion .of the window frame, and in which roove the adjacent edge portion of the wind wv sash moves. This groove 13 may be cut in the window frame, but it is usnally formed by side strips B 13, either laid fiat on the sash frame or set in a recess of the frame. In windows having two sashes the strip B is the partition strip or tongue between the sashes, and is then usually set in a recess. These stri .s B B, when present aresecured in any we lknown manner. Such grooves 13 are present on both edges of the window, one in the vertical portion of the sash frame on the left, and another in the vertical ortion of the sash frame on the right. he bottom A of the sash frame is well known as the window sill. This sill A is usually provided with a strip A, which rises above the surface of the sill A and .is located at that side of the sill which is next to the room, and it is secured to the sill in any suitable manner. This sill strip A -D indicates a tongue securely held in any proper manner'to the surface of the window frame. This tongue D-may be a single solid I piece or strip of metal, but preferably it consists of a piece of metal bent or folded back upon itself, and thus consisting of two thicknesses D and D of metal, whose free edge D is rounded and smooth as shown. The preferred mode of securing this, tongue D D to the window frame is as follows: From the loottom of the portion D -extends out a flange D, at substantially a right angle from the plane of the portion D From the bottom of the portion D extends but a flange D, at substantially a right angle from the plane of the portion D The foot flanges D and D are secured in place either by nails, or screws .and'the like, or in case of constructions'where these flanges D and D are sunk into the wood, or in part covered with binding strips which contribute to hold these flanges in place, such nails or screws may, in many cases, be dispensed with. In the drawing, one mode of holding these flanges D and D in position on thewindow frame is illustrated. This mode consists in adding the flange D extending at a right angle from the part D and the part D. Thus the tongue D and the flange D extend in parallel planes. The tongue D extends in one direction from the plane .of the flange D, and the flange D extends in the other direction from the plane of the flange D. This flange D extends on the side of a recess A in the window casing. On the vertical side of the window casing B, a strip of Wood 13 secured in the recess B holds the flange D in place. On the window sill A a strip of wood A secures the flange D in position in the recess A". IVhatever be the manner of securing this tongue D in place, it is to extend out from the plane of the casing A or B, and in a'plane at substantially a right angle from the latter, as indicated inthe drawing.

In the window sash O I form a compound groove. The first part H of this roove' begins at the outer. edge of the sash frame and extends inwardly as far as may be. At the rear end of this groove H, I provide on the right side of this groove H, a groove H and I provide on the left side'of this groove H, a. groove H The inner or back sides of these grooves are in the plane of the back side 0 the groove H. The part1 or outer side of each of the grooves H and H is preferably rounded and the forward outer side I of each of the said grooves H and H is preferably rounded or inclined toward the main groove H into the adjacent side of which latter it merges. The front corners I I of the groove H are rounded or curved substantially as shown.

I I provide an insert K, such as is illustrated in Figs. 2, 4 and 6. This insert K is preferably made of sheet metal. It has a broad back K substantially flat. The corners K, K, when the insert is made of sheet metal, will be somewhat rounded, and each side K will be bent back from the corner toward the mid-line of the main groove.

Each portion K of the insert then extends toward the front end of the groove, in preferably a straight line Near the mouth of the groove, the portion K begins and curvilinearly inclines outwardly away from the mid-line of the groove. For convenience of reference, I shall term the portion K a plate or side portion of the insert. The outer width of the insert from each corner K is but slightly less than that of the groove from corner H to the corner H This orm of. insert K, readily does so.

When the insert K is in position within this groove H, one of the corners K fits in the corner H of the groove H, and the other of the corners K fits in the corner H of the groove. One curved end K of the insert K is preferably in contact with the adjacent curved corner 1*, ofthe groove. H, and the erably in contact with the other curved shown in Fig. 7. The insert- K when located casion calls, the tongue D. The sides or walls of the insert K are elastic. As the tongueD enters the groove H of the insert, it presses against the opposite walls or sides K K and moves them outward and away from each other the thickness of this tongue. The walls or sides K, K, being elastic readily thus yield. As the'curve of each side K is thus straightened, the said side is, while the tongue occupies the groove, made somewhat longer relatively to the distance from the base of the groove to the endof its mouth, and the curved lip K will be moved on and will slide a little around the curved edge I of the groove H,;and at the same time will remain in close contact'with the said curved ed e I. Thus all side or lateral oscillation of t e sides I I of the insert is obviated. There is also no oscillation of the backK of the insert, and consequently any such strain upon the insert is avoided. In cases where, in the manufacture of my insert and groove, the lips K do not abut against the sides of the groove, that feature of the insert which consists of the specially formedback K having corners K, K will yet be of great advantage, as will be obvious. It will be at once obvious that this combination of these peculiarly shaped members thus qualified, also affords other certain marked and valuable advantages. The first of these roove H being made to receive this peculiar 7 other curved end K of the insert K is prefcorner I of the groove H, substantially astherein is now in readiness to receive, as 00-- K of the insert, the insert and the said corners of the groove and of the insert closely interfit, the insert can neither fall out of the groove nor can it, the insert, sag at all from place. The second of these advantages is that the sides of the insert at and in the neighborhood of the parts K are free to move outwardly, when the tongue D is entered between them. The space between each wall I of the groove and the adjacent wall or part K of the insert is quite sufficient to readily admit the tongue as shown in Fig. 2. The elasticity of the walls K, K of the insertcauses these walls to press closely against the tongue, and to keep it in contact therewith.

The curved lips K, K, not only permit the tongue to enter, but form a gu'ideway for the tongue to enter easily and without any possible interruption. is of advantage when the tongue is on the side of the sash frame and the sash is being put into place, because itdoes not compel special and unremitting care to see that the tongl-ie enters the insert while the sash is being put into place.

in the majority of instances, I, locate a tongue on the window sill and an insert in the bottom of the sash. Insomuch as every time after the sash is lifted, and then lowcred, the tongue must enter the insert, it is evident that this elastic guideway of the in sort is of primary importance, because it prevents all danger of the window sash not seating itself down upon the sill, and also not completing the sealing of the sill and sash against the ingress of air, dirt and moisture.

it will be obvious from the preceding description that the combination of the groove,

with insert, and the tongue for insertion therein, is to be used on the vertical window frames, in connection with the respective adjacent vertical edges of the window sashes. And the said combination is to be used when desired at the sill of the window frame in connection with the bottom of the lower sash, and also to be used when desired at the upper or top frame of the window, in connection with the u per edge of the upper sash. lVhi-le it is pre erable' to use the said combination at all of these places on a given window, the use of the said combinationmay be omitted from certain part or parts of the window and its use confined to another or other parts.

It is further obvious, and I intend to in- Thi guideway K, I

clude it in my invention, that the groove and insert may be located in the window frame, and the tongue be located on the sash, but such location of the groove and insert in the window frame is not as desirable as the loca tion ofthem in the window sash, because the insert is not so readily located in the groove in the window frame, as it is in a groove in the window sash, because the insert is readily inserted in the end of the groove of the sash,

and when inserted a slight detent or projection prevents it from slipping lengthwise in the groove.

Certain obvious modifications of the construction hereinbefore specified, and which modifications, although not the preferred constructions, are advantageous, are as follows:

In Fig. 9, I have shown a construction wherein the insert carries one elastic plate K instead of two. In such a case, the sealing tongue D makescontact with one side of 5 said late, and also when the curve K of In Fig. 10, a construction is obtained wherein the enlargement at the back of the main groove is'at one side and to a greater than in the other figures.

j whose back is extended at K to one side and interfits the back of said groove H and its 5 said enlargement. Therein this insert is thus held in place. The elastic plates K, K of this construction are competent to receive the sealing tongue between them and to make close contact therewith.
